For example, you could create a delta pulse, and then filter using a bandpass filter:</p> <pre><code>clearvars; % define delta function sig = zeros(1, 100); sig(end/2) = 1; % apply bandpass filter sampling_freq = 50e6; center_freq = 3e6; bandwidth = 100; sig_filt = gaussianFilter(sig, sampling_freq, center_freq, bandwidth); % plot the signal figure; plot(sig_filt); % plot the spectrum spect(sig_filt, sampling_freq, &#39;Plot&#39;, [true, false]);</code></pre> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/center-frequency-and-bandwidth-of-the-linear-array-transducer#post-6996 Wed, 07 Aug 2019 07:37:18 +0000 prabhakar.amarana 6996@http://www.k-wave.org/forum/ <p>I need to use a linear array transducer to perform simulations.<br /> How can I specify the center frequency and % bandwidth of the linear array transducer in k-wave? </p>
